Lua Expression Syntax Now Live in WatchMaker Studio

Studio
1

Based on your feedback, WatchMaker Studio now uses Lua expression syntax instead of JavaScript.

This change keeps Studio aligned with legacy WatchMaker faces and makes expressions more consistent across the platform.

Thank you for all the feedback — it genuinely helps shape the direction of Studio. Looking forward to seeing what you build with it!

Please note: full Lua scripts still cannot run inside Watch Face Format exports due to platform limitations. Only expressions are supported.

Thank you. And thank you for fixing the calculations I was using for animation in studio. Now I won’t have to try to convert between the two depending if using the app or studio.
